MAP-CABINET.

Specification of Letters Patent.

Patented July 1'7, 1917.

Application filed April 7, 1916. Serial No. 89,563.

To all whom it may concern:

Be it known that I, THoMAs H. CosrELLo, a citizen of the United States, residing at the city of Chicago, in the county ofCook and State of Illinois, have invented certain new and useful Improvements in Map-Cabinets, of which the following is a specification.

My invention relates to means for storing maps in such a manner that the same may be protected and conveniently housed while not in use, and that they may be readily eX- tended when desired for reference. It is particularly designed for use with maps that are mounted on spring rollers which provide for their automatic return. The object thereof is to provide a rack upon which a number of the said rollers and maps may be mounted and normally stored within a minimum of space on the wall from which they are suspended; that they may be protected against dust and idle interference; that the map rack may be automatically inclined forward to the using position as the door is unlocked and opened, so that the maps do not drag or chafe upon each other or the map rack, when extended;

and to provide a case which shall be simple and comparatively inexpensive in construction.

The principles of my invention are illustrated in the drawings, in which-- Figure 1 shows a front view of my improved case, the central portion being broken away;

Fig. 2 is an end View of the same, showing the movable parts in dotted lines;

Fig. 3 is a cross section of Fig. 1 on the dotted line 33, the map rack and door being open.

Further describing my invention with reference to the drawings: 1 is a back or foundation secured to the wall 2. 3 is a top or cornice mounted on the upper part of the i said back. A map rack comprises the end pieces 4 and 41, the top piece 5, and the bottom member 6. The said pieces are framed together in rectangular form to form a frame within which are mounted the maps 7 on the rollers 8. The map rack may be of the same length as the foundation piece, and at its lower inner part should be attached by hinge 9 to the lower part of the foundaii tion piece 1. A pair of links 10, pivoted at 11 to the foundation piece, are provided with slots 12, within which screws or studs 13 are attached to end members 4 and at, whereby the forward movement of the end member is limited. A cover for the face of the rack consisting of the door 15 is hinged at 16 to the front edge of bottom member 6 of the map rack. The normally upper edge thereof should be provided with a latch or catch 17, which is adapted to engage the loop 18 on the front edge of the cornice 3.

Assuming the relative position of the several members of the device to be as shown in Fig. 3, it will be seen that the maps can be drawn downwardly and outwardly with little or no tendency to bear upon or be injured by the maps which are relatively beneath them or by the framing of the map rack itself, the latter being provided for by the chamfered edge 19 of the lowermost member of the map rack. When in the position shown preparatory to closing the cabinet, the door is swung upwardly against the face of the map rack, and when pushed back to the position shown in Figs. 1 and 2 the rack will be forced under the cornice and held in position by the door and the catch 17. On the other hand, when the catch is loosened, the center of gravity of the map rack, being placed forwardly of the point of pivotal attachment, viz., the hinge 9, the rack automatically will be projected forwardly until it takes the position shown. It is evident that the rack may be inclosed by end pieces which are permanently secured to the back or foundation member 1, so that the map rack may be inclosed at its ends as well as at the top.

I claim:

1. In a map cabinet; the combination with a wall of a map rack pivotally connected to the wall so that it will normally be forwardly inclined, means for limiting such forward inclination, a door hinged to the said rack and means for connecting the door to the wall to secure the map rack in the vertical position.

2. In a map cabinet; a map rack, means for pivotally connecting the same rearwardly of its center of gravity to a support, a door to inclose the face of the said map rack, and detachable means for connecting the free edge of said door to the support so that when disconnected the map rack will be free to assume a forwardly inclined position.

3. In a map cabinet; the combination of a foundation wall piece, a map rack pivot ally attached at its lower and rear portion to the lower portion of said foundation piece and normally forwardly inelinable therefrom, means for limiting such forward inclination, a door to coverth e front of the map rack hinged to the lower front portion thereof, and means for detachably connecting the free edge of said door to the upper part of the foundation piece whereby the map rack will be held in the closed position.

l. In a map cabinet; a wall or foundation piece, a map rack pivotally attached at its lower rear edge'to the lower part of the foundation piece, a cornice secured to the upper part of the foundation piece, a door pivotally attached to the lower part of the map case, and means for detachably secur- ,ing the free edge of the door to said cornice.

5. In a map cabinet; the combination of a foundation wall piece, a map rack pivotally attached rearwardly of its center of gravity to the lower portion of said foundation. piece, a door to cover the front of the map rack hinged to the lower portion thereof, and means for detachably connecting the free edge of said door to the upper part of the foundation piece.

6. In a map cabinet; the combination of a foundation wall piece, a map rack pivotally attached rearwardly of its center of gravity to the lower portion of said foundation piece, a door to cover the front of the map rack hinged to the lower front portion thereof, a cornice secured to the upper part of the foundation piece, and means for detachably connecting the free edge of said door to the said cornice.

In witness whereof, I have hereunto subscribed my name in the presence of two subscribing witnesses, this 3rd day of April, 1916.
